I'd like to see the time-limited Notable Homes sold in batches, say a minimum of 3 at a time.
It might have made sense to restrict the number for sale when there were only a few notable houses in the game, but now we have a lot more and they come around very, very slowly. Having to wait almost 2 years for a particular house to come around seems excessive. Real life issues can very easily mean people miss logging in during the sale slot and then they have to wait even longer.
Because these houses are expensive to buy and very different from each other, it's not likely that people will just settle for one that 'will do' or buy multiples. If you really want a Telvani mushroom tower, a Psjiic retreat or a sailing ship for your characters, then very probably only that specific house is going to get you to make a purchase.
I notice on the Crown Store controller menu that the Notable House always appears with 2 empty slots alongside. Please consider at least filling those empty spaces and offering two more Notable Homes at a time.
